Hello everybody

Please tell me what the problem might be

I have a mail server on which the filebeat agent is installed, it transfers data to another server on which logstash and elastic are installed

I randomly display data with a delay of more than 7 seconds

As you can see in the screenshot, the recording time of the event on the mail server differs from the recording time in the elastic itself by 7 seconds

What could this be related to?

All VMs are on the same network in the same VLAN on the same host in VMware

This could be a number of things:

- buffering in filebeat
- buffering in logstash
- etc

I would recommend you to parse the events using a pipeline (either logstash or elasticsearch) and use the date filter/processor to set the @timestamp to the one in the log record.

This will make sure the records are displayed in the correct time moment.

And could you provide more practical recommendations. What parameters to pay attention to?

Thank you!
